Abstract: Abstract Recognition heuristic (RH) is frequently used when human make decisions. The RH as one of the simplest heuristics has attracted the attention of many researchers, it only uses recognition to make decisions. RH can be defined as follows: if only one of the two items is recognized, individuals infer that the recognized item hasstronger evidence therefore it should be chosen. For example, the individual is asked to judge whether City A or City B is larger. City A is recognized city, and City B unrecognized city. If the individual chooses the recognized City A as the larger city, it indicates that the individual uses the RH. Many measures have been used in RH. The measures included but not limited to are: adherence rate, discrimination index, hit rate and false alarm rate. These measures are limited in distinguishing the key concepts recognition and knowledge. To overcome this limitation, we introduce measures from a parametric multinomial model in this paper. The model is called Multinomial Processing Tree (MPT) model. MPT model is a family of effective statistical model measures and analyzes both explicit and implicit cognitive processes. MPT modeling methods have been successfully applied in many subject areas such as cognitive psychology, cognitive neurology game theory, sociology, artificial intelligence and artificial intelligence network. We have built a version of MPT model in this paper specifically for measuring relevant cognitive processes in RH. We name it r-model. The r-model introduce in this paper contains three sub-model with each of the models targeting three different cases: two objects are recognized (knowledge case), only one object is recognized (recognition case), and none of the objects is recognized (guessing case). The premise of using R-model is to use the pair comparison task as an experimental paradigm. After introducing the model, we explain how would one analyzes data using r-model. The strength of r-model is the capability of analyzing individual differences. Most existing methods can only analyze data at the group level therefore ignore individual differences. The degree RH used in human cognition highly individualized. RH researchers started to pay more attention to individual differences. Two methods are commonly used when considering individual differences in RH studies: Hierarchical Bayesian models and Hierarchical latent-class approach. Our proposed r-model is MPT implementation of the above mentioned two methods. The method of hierarchical modeling is used to define a separate MPT model and individual parameter estimates for each subject. It assumes that the individual parameter estimates for these individual MPT models come from a common distribution. The hierarchical latent-class approach is to use a finite hybrid model and assumes that the subject belongs to a limited number of potential classes and the same class of subjects have the same parameters. At the end of the paper, we propose the future research directions of using r-model in RH research. Specifically, we propose 1) how to modify model parameters to consider other measures such as response times and heuristic strategies; 2) How would one consider non-cognitive factors such as environmental conditions and individual characteristics.
